BARTH, 0F BISMARCK, NORTH DAKOTA i METATARSAL-PAD LOCATOR Appncatiqn filed July 26,

Thisy invention relates to an apparatus or device designed for use in diagnosing foot troubles particularly for determining the point of Contact between any part of the foot f and the in-sole of a shoe,'toaid in properly placing a metatarsal pad into the shoe and also to aid in the cutting of holes in the in-sole of the shoe directly under corns or callouses for the purpose of providing a .pocket or space therefor.

"The present invention is generally of the Anature disclosed in my'vPatent No. 1,684,339

for pedo-graph and metatarsal pad locator, issued September 11, 1928, and it constitutes an improvement thereover.

' It is particularly aimed to provide a novel construction or mounting for the flexible arch-engaging member and to provide av novel means'for inking' and preventing drying of the ink transfer member, and further to provide a novel construction wherein a cam is used to both flex the arch member and maintainvthe inking member in engagement Figure 3 is a plan view of the device showing the ink ltransferring sheet in retracted position, f

Figure 4 is a longitudinal sectional viewV taken on the line 4 4 of Figure 3, showing the ink transferring sheet in position for making an impression,

Figure 5 is a longitudinal sectional view taken on the line 5-5 of Figure 1,

Figure y6 is a crosssectional view taken on the line 6 6 of Figure 5, and

Figure 7 isa cross sectional view .taken on the vline 7 7 of Figure 4.

yReferring specifically to the drawings, 10 .11 generally designates a suitable receptacle,

partly broken 192s. serial 10.295,3'86.

top for reception of the foot.

Located inthe receptacle with their longitudinal edges disposed in grooves 11 in side wal-ls 12 of the receptacle 10, are coacting plates 13 and 14, the former being slidable byrreason of its mounting in the aforesaid grooves 11 and also being slidable throughY a slot 15in one Vend wall 16 of the receptacle 10. Such plate 14 may have a finger opening 17 to facilitate its manipulation.

The separation of the plates 13 and 14 provides an opening or space 18 between them to accommodate an arch-engaging member 19 Which is preferably off-flexible metal and normally flat as in Figure 5 but capable ofbeing bowed as in Figure 4, in order to fit the arch. Such member 19 khas downturned flanges 20 andthe same is supported on transverse rods or bolts 21 fastened in the side -walls 12 of thejreceptacle. rl`he adjustment of the plate 14 is relative to a scale 22. f

The flexing of the element 19 iseffected ranged vcam `23 journaled by means of trunnions 24 and 25 in the walls 12, the latter trunnionfhaving a cranlrior handle'26 fixed thereto for operation to move the .cam 23. The handle 26 travels relatively tofor across a detent plate. 27 carried by one of the sidev members 12. At the free end of the handle 26, a screw 28 is detachably threaded as at 29 and the threaded element is extended to form la pin 30 to selectively` engageholes 31in the plate 27 according to the position in whichV the cam 23 is toy be held, depending upon the curvature of the arch ofthe shoe into which the metatarsal arch is to be built;

When an impression is made, a sheet of j paper is placed across the plates 13, 14 and 19 andan ink transferringl sheet 32 is adapted to be arrangedover the paper sheet. The sheet 32, at the undersurface, as viewed in F igure4, is adapted to carry ink thereon and hence when the foot engages the sheet 32 and presses the rsame against the paper, in combination with the curvature of the. plate 19, f an impression will be made on the paper sheet to show thevarious points of the foot and therefore form a basis for the application of metatarsal pads or the other uses to which the invention may be put. l

TheY sheet 32 is guidedover rollers 33 fas-y tened in the side members 12 and Abeing attached by means of cables or flexible elements 34 to a roller or drum 35 having trunnions 36 journaled in the side walls 12 of the receptacle .10. The roller 35 is a conventional spring-returnk roller, urged to rotate so asv to normally bind the cables 34 thereon as shown in Figures 1 and 5. Y v I f i The free end of the sheet 32 is ,attached to a cross arm 37 of a bail 38 whose terminals i are journaled as at 39 in brackets 40 fastened yto the side members 12. The spring roller 35 dueto its torsional action normally main-vYV tains the bail 38 in the position shown in Figures 1 and 5. The bail may, however, be swung one hundred and eighty degrees to the position shown in Figure 4 where the tension of roller 35 yis overcome and the bail will remain in such position until returned to the V position of Figure 5. It will be noted as in Figure 5, the sheet' 32 does not extend across' .the plates 13 and 14:

while in Figure 4 it does. g

An inlring pad is shown at 42 and while it may be of any approved construction, has

an .absorbent ink receiving fand applying 1 body 45 carried by a rigid back member 46.V

Fastened tothe back member 46 isa blade spring 43, as best shown in Figure 6, whose terminals are entered inslots 44 of the side members 12. Such spring 43 normally tends to straighten and thereby urge the inking pad 42 toanv elevated position as in Figure 4,

or out of Contact with. the sheet 32. Nor-V mally cam 23 isin the position shown in Figure 5 where it engages theback 46 and -V accordingly depresses the inking pad 42 so that its surface 45 engages the ink receiving surface of the sheet 32, thus continually inking such sheet and preventing the drying of ink therefrom. The pad 42 may be inked from time to time or any means provided to accomplish the inking thereof.

47 designates a bracket-that is removably mounted on an end of the receptacle 10, be'- tween studs 48, and is .used when it is desired to determine the size of shoe to be worn by a customer, a conventionalV measuring scale (not shown) being laid on the plates 13 and 14 for this purpose, the heel of the foot en-V gagilng the bracket when the device is lso use Y Particularattention is called to the fact thatthe cam 23 performsV the dual function of lowering the inking pad and maintaining it normally in contact with the sheet 32 and releases such pad and bows the element 19 to form the same. contourfas the arch of the Vshoe into which the metatarsal pad is to be built. A Y. The invention operates generally in the '65 manner disclosed inmy aforesaid Patent No.v i

1,684,339. Normally the cam 23 Vmaintains awayfroni the plate 13 and further operationY of the cam 23 elevates or bows the member 19 which may be `accomplished prior or after a sheet of paperis disposed over'the plates 13,

14 and 19; and the foot is engaged with the sheetV 32, moves tothe position of Figure 4 Vby throwing the bailV 38ffromthe position shown in* Figure 5,-one-hundred andeightyf v degrees to that shown in Figure 4. y V- Various changes Vmay be resortedto provided they fall within the spirit and scope of f the invention.
